摘要:	摘要： ► Novel PtPd bimetallic nanoparticles decorated on multi-walled carbon nanotubes (PtPd-MWCNTs) catalyst was prepared by a modified Watanabe method. ► The resulting biosensor exhibited a good response to glucose with a wide linear range (0.062–14.07mM) and a low detection limit 0.031mM. ► The biosensor also showed a short response time (within 5s), and a high sensitivity (112μAmM−1cm−2). ► The biosensor exhibited high reproducibility, good storage stability and satisfactory anti-interference ability. A sensitive, selective and stable amperometric glucose biosensor employing novel PtPd bimetallic nanoparticles decorated on multi-walled carbon nanotubes (PtPd-MWCNTs) was investigated. PtPd-MWCNTs were prepared by a modified Watanabe method, and characterized by XRD and TEM. The biosensor was constructed by immobilizing the PtPd-MWCNTs catalysts in a Nafion film on a glassy carbon electrode. An inner Naﬁon film coating was used to eliminate common interferents such as uric acid, ascorbic acid and fructose. Finally, a highly porous surface with an orderly three-dimensional network enzyme layer (CS-GA-GOx) was fabricated by electrodeposition. The resulting biosensor exhibited a good response to glucose with a wide linear range (0.062–14.07mM) and a low detection limit 0.031mM. The biosensor also showed a short response time (within 5s), and a high sensitivity (112μAmM−1cm−2). The Michaelis–Menten constant (Km) was determined as 3.3mM. In addition, the biosensor exhibited high reproducibility, good storage stability and satisfactory anti-interference ability. The applicability of the biosensor to actual serum sample analysis was also evaluated. 其他題名： Biosens Bioelectron 出版者： Kidlington: Elsevier B.V 出版日期： 2012-03-15 出處： Biosensors & bioelectronics, 2012-03, Vol.33 (1), p.75-81 版權： 2011 Elsevier B.V. 版權： 2015 INIST-CNRS 版權： Copyright © 2011 Elsevier B.V.
